IMPROVEMENT IN WASHING-MACHINES.

The Schedule referred to :in these Letters Patent and making part of the same.

- thereon,

The nature of this invention consists in the arrange- 'ment ofthe wash-board and plunger to produce a rocking and kneading movement, to compress and rub the clothes more perfectly.

To enable those herein skilled to make and use my said improvements, I will now more fully describe the same, referring to the accompanying- Figure 1 as a sectional elevation, to

Figure 2 as a plan, with the washing-machine cover removed, and to Figure 3 as a side view of the devices operating the churn-flasher.

I construct the'vessel or box A of the washing-'machine in any desired form, usually resting the same in an inclined position upon the legs, as indicatedng. 1.

To operate said machine, I arrange at the upper end of said vessel A the driving-shaft B, with iiy-wheel B', and handle b.

On said shaft, within the vessel A, I arrange the crank b', and connect hereto the forward end, O, of a connecting-rod.

. Said end piece C has a screw, c, which connects this piece with the 'rear end, C', of the connecting-rod, the set-screwd being adjustable in the slot cl of the end O', in order to lengthen or shorten the rod.`

At its lower end the piece C' has a spring, c?, pressing upon the bearing-stirrup D, the spring c2 being held by a proper. pin to the piece C', and beingconned in the mortise d, formed by ribs ofthe stirr'up D, the said stirrupy will then becarried back and forward and perbrm an angular vibration at the same time, under the impulse of the crank b'.

Said stirrup Dis screwed to the plunger E, which has a ridged surface, to rub and press against the clothes placed before the same.

The plunger E moves on slides E', secured to the bottom of the vessel A.

In order that the clothes may receive from both sides an elastic rubbing' pressure, I construct the washboard F, having the usual ridged surface, and having at its back the rockers f.

A spring, f', `is arranged to connect the upper edge of said board with thesde of the vessel A.

\Vhen the plungerrE, moving down, presses the clothes before it against the board F, this is forced back, and, owing to the changing angle of inclination of the plungervE, the board F is caused to make a rotary vibration about a horizontal axis, thus acting toA thoroughlyr knead and-compress the clothes between the' board and plunger, in a manner highly conducive to the cleansing of the same.

In order to operate a churn-dasher, H, by the shaft B and its iiy-wheels, I arrange on the body of the washing-machine a guide, I, upon which lthe cross-head k is caused to travel by a rod, K,lwhich connects with the pin k1, upon the Hy-whecl B'.

The connecting-pin 7a2, of the parts k K, is used also as point of attachment of dasher H; and a simple reciprocating motion of the dasher is thus achieved by the operation ofthe shaft B.

NVhile the operations of the two machines are independent of each other, still it is considered.. an important economy to use the operatingLdevices `of a washing-machine to operate a churn-dasher.V In order to carry no dead weight, if the washingmachine is not in'use, the connecting-rod O C' will be disconnected from the crank b in operating the churn. Similarly the churning attachment may be disconnected when not'in use.

Having thus fully described my invention,

What I claim, 'isrlhe arrangement of the plunger E, moved on ways E bytherod C C', crank b', and crank-shaft B, the` parts being joined to said plunger bythe strap D and springe, combined with theboard F, having rockers f and springf, substantially' a-s set forth.

In witness of said invention, I have hereunto set my hand, in the presence 0f- JUSTUS SMITH.
